Depositional and diagenetic processes in carbonate systems

Modern carbonate systems such as reefs provide livelihood and ecosystem services, such as coastal protection and food security, for hundreds of millions of people. Fossil carbonate systems are important archives of environmental change and form a valuable resource for renewable energy exploration and exploitation such as geothermal heat but also for CO2 sequestration. Over the past decades, our understanding of carbonate systems has improved by the combination of traditional fieldwork with new techniques such as 3D seismic analysis, modeling, high-resolution 3D microscopy, and advanced geochemical methods. This session seeks to present studies applying state of the art methodologies in addressing open questions in the broad field of carbonate sedimentation and diagenesis. We especially encourage contributions to the following themes: 1) Anthropogenic influences on modern carbonate systems or carbonate secreting organisms, 2) Impact of diagenesis on palaeo-environmental and palaeoclimatological carbonate archives, (3) Biogeochemical and physicochemical processes driving carbonate precipitation and alteration processes, and (4) Petrophysical and geophysical characterization of carbonate systems.
